Despite my extreme (32 year long) computer use, I only had RSI symptoms when using a mouse and under stress. Since I use my macbook trackpad and have no stress, I can sit in any position for any time and do anything and have 0 symptoms. I am very interested in coding without keyboards etc because these days I happen to think a lot more about my code before trying it and that means I walk around a lot; sitting down or walking to my standing desk both seem cumbersome.

Are you a home-row typist? I am not (my hands float freely above the keyboard, generally angled with respect to it, so my wrists are not bent), and I attribute my 23 years of RSI-free near-daily computer use to being home-row-free.

(Albeit, like you, mice started giving me trouble after about 8 years of mousing. The problem was gripping while moving the wrist. Solution? Trackball.)

(EDIT: Tangentially, I keep my eyes in shape with "preventative" eyewear: I don a pair of (weak) reading glasses ~33% of the day to shift the focal point of my monitor further away. Keeps eye strain at bay.)
